How can you use the transformation to prove two triangles are congruent

You could use a translation to move one to the same position as the other and compare if they have the same orientation (like both are pointing up).
If not, you could use rotation to do so, then use translation. Sometimes even reflections might work, but that's a bit more complex.

What is the slope of 3x+8y-1=0

Fudgin [204]

One of the most common ways to find the slope is to put the problem in standard, slope-intercept form, which is y=mx+b. The easiest way to describe this process is to isolate y.
Here's how you do it for this problem:
$3x+8y-1=0 \\ (3x+8y-1)+1=(0)+1 \\ 3x+8y=1 \\ (3x+8y)-3x=(1)-3x \\ 8y=-3x+1 \\ (8y)/8=(-3x)/8+(1)/8 \\ y= -\frac{3}{8}x+ \frac{1}{8}$
Since m is your slope, the answer would be -3/8.
Hope this helps!

the median weekly earnings for american workers in 1990 was $412 and in 1999 it was $549. Calculate the average rate of change b

mina [271]

The rate of change between 1990 and 1999 is 15.22

Step-by-step explanation:

The rate of change in this case is given by change in quantity divided by change in time

So,

$Rate\ of\ change = \frac{Increase\ in\ money}{Increase\ in\ time}\\=\frac{549-412}{1999-1990}\\=\frac{137}{9}\\=15.22$
